  • RE: TIDA-00233: Design support for Vout:28V, Iout:50A

    Resolved
    Dear Furkan, In principle most of the features are covered by the TIDA-00233 circuit. However in your case I would tend to use the circuitry more like in our TIDA-01552 reference design: https://www.ti.com/tool/TIDA-01552 . You need to change the power…

  • TIDA-00233: Need guidance to use as reverse power protection with Keithley Power supply with 30V, 6A

    TI Thinks Resolved
    Part Number: TIDA-00233 Other Parts Discussed in Thread: LM5069 Can we use this Part TIDA-00233 to Power supply channel of 30V,6A from reverse power?? We also have other application, that we need to control power supply voltage with analog input with resolution…

  • LM5069: TIDA-00233 Operation under negative input

    TI Thinks Resolved
    Part Number: LM5069 Other Parts Discussed in Thread: TIDA-00233 , , TPS2660 , LM5050-1 , LM74700-Q1 Hi I refer TIDA-00233. I want to see circuit behavior under negative input. (Especially, confirming a state that the input can not reach output side.) …

  • RE: LM5050-1: - 1.2KV differential mode surge damaged pin1,2

    Resolved
    Hello Yue Tang, The schematic does not show any TVS diode at the input to take the surge energy. The 1.2kV is lot of energy and a TVS rated at 5000W or more would be required. Thus, voltage rating of the LM5050 would have exceeded during surge testing…

  • RE: LM5060: Backfeed from VOUT coming back through OUT / GATE

    Resolved
    Hi Bryan, Your image attachments are missing. Can you please re-post them. From your understanding, it looks like the problem is due to reverse current blocking. The configuration in Figure 41 blocks reverse current only when the controller is OFF. To…

  • RE: LM5050-1: Can I parallel the mosfets?

    Hi Richard, Difference between LM5050-1 and LM74700 is that LM74700 has a better gate current to drive bigger MOSFETs for high current applications. LM5050-1 can do the job, except that turn on time is slow due to lesser gate current strength. Slow…
